ROBERT H. BIEGEL AND DON C. PHILLIPS, OF DENVER, COLORADO.

ADJUSTABLE GUARD FOR EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 511,261, dated December19, 1893.

Application filed April 26, 1893. Serial No. 471,961. (No model) To allwhom it may concern.-

Be it known that we, ROBERT H. Ernest. and

' DON C. PHILLIPS, citizens of the United States of America, residing atDenver, in the county of Arapahoe and State of Colorado, have inventedcertain new and usefullmprovements in Adjustable Guards for Eyeglasses;and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, refcrence being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specifica- Our invention relates toimprovements in guards for eye-glasses, and the object of theimprovementis to provide'a device of this class which shall beadjustable to fit difierent persons, and the device will be fullyunderstood by reference to the accompanying drawings in which isillustrated an embodiment thereof.

In the drawings, Figure 1 is a front elevation of a pair of eye-glassesprovided with our improved adjustable guard. Figs. 2, 3 and 4 showdifierent forms of construction in detail, and on an enlarged scale.Fig. 5 is a section taken on the line 32-96, Fig. 3.

Similar reference characters indicating corresponding parts in theseviews, let the numeral 5'designate the eyeglass-frame to which the guardis attached by the screw 6. The bar 7 of the guard is provided withasegmental arm 7 which is slotted or apertnred to receive the fasteningscrew. This segmental arm may have any desired number of apertures, orthe slot therein may be of any required length. The guard bar and thearm may be formed integral or in two parts, to be afterward connected inany suitable manner.

As shown in the drawings, the guard bar and the arm occupy differentplanes, the two bars extending inwardly toward each other,

while the arms are attached directly to the they may be attached, orwith which they are formed integral as before stated. \Vedo not wish tolimit ourselves to any exact shape for the arms 7. Three differentstyles are shown in Figs. 2, 3 and 4t, and many others may undoubtedlybe made which will answer the purpose equally well, without departingfrom the spirit of the invention.

The use of our improved guard will be readily understood. By looseningthe screw 6 in the form shown in Fig. at, the arm may be made to slideon the screw until the guard bar 7 occupies any desired angle with theplane of the frame, when by the tightening of the screw, the guard isheld in the adjusted position. In the case of the apertured arms, theadjustment is the same except that the screw must be removed from oneaperture and inserted in another. I

In the form shown in Fig. 3, the arm 7 con- .sists of a single wire heldin place by a plate secured by the fastening screw. To adjust the guardin this form, it is only necessary to loosen the screw and move the armto the desired position, after which the tightening of the screwmaintains the arm in the desired place.

Having thus described our invention, what we claim is- The combinationwith the eye-glass frame of the adjustable guard consisting of the barand the segmental arm apertured to receive the fastening screw,substantially as described.

In testimony whereof we affix our signatures in the presence of twowitnesses.
